Which V2 version? Warning is not supposed to be there in m10 or later.

I'm afraid no.

No, it's just a way 'stage' works. The problem is that windows has severe 
command line length limitations so all compile and link actions use response 
files. The response files are consisred regular targets by V2. Finally, the 
'stage' rule always relinks the executables to the destination dir, and so it 
creates respose file in the destination dir, too.

How pressing is this issue? I'll be working on stage for m11, and thinking 
about making it simply copy executables on windows. This, accidentally, will 
fix your problem.
